What if Apple's mobile phone weather forecast is not accurate?

The weather forecast of Apple's mobile phone is inaccurate. You can reposition the current position.

Weather forecast (measurement) or meteorological forecast (measurement) is to use modern science and technology to predict the state of the earth's atmosphere in a certain place in the future. Since prehistoric times, human beings have begun to predict the weather and arrange their work and life accordingly. Today's weather forecast mainly uses the collection of a large number of data, and then uses the understanding of atmospheric processes (meteorology) to determine the future air changes.

Weather forecast is an important means for meteorological work to serve the national economy and national defense construction. Weather forecast is divided into regional weather forecast and local weather forecast according to the forecast scope. According to the needs of customers, there are daily public weather forecasts and professional weather forecasts.

Early weather forecast:

Numerical value is the language of science. Weather forecast is inseparable from the quantitative observation of atmospheric motion by instruments. We can set the invention and application of meteorological instruments as the start time of early weather forecast.

/kloc-in the 5th century, the west invented the pressure plate anemometer, which can quantitatively measure the velocity (energy) of atmospheric motion for the first time. 17-18th century, scientists have successively invented various instruments for quantitatively measuring weather phenomena, marking the beginning of a new development period for the detection means of meteorological scientific research. The British physicist Hooke (1635- 1703) invented the hygrometer.
